This invention appertains to new and useful improvements in float valves especially adapted for use in drinking troughs for live stock.

The principal object of the present invention is to provide a float valve structure of the character stated which will be positive acting and not susceptible to the ready development of defects such as occur in present day types of float valves.

Another important object of the invention is to provide a float valve structure of the character stated wherein friction is reduced to a minimum thus reducing wear and other defects which occur from close fitting parts under immersed conditions.

These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:--

Figure 1 represents a vertical sectional view through a watering trough showing the float valve in side elevation.

Figure 2 is a vertical sectional view through the valve structure showing the float and associated details in elevation.

Figure 3 is a vertical sectional view similar to that as shown in Figure 2, but showing the float in partly lowered position.

Figure 4 is a section on line 4-4 of Figure 2.

Figure 5 is a horizontal sectional view taken substantially on line 5-5 of Figure 2.

Figure 6 is a top plan view of the valve element.

Referring to drawings wherein like numerals designate like parts, it can be seen in Figure 1 that numeral 5 represents the trough with numeral 6 the water supply pipe extending upwardly through the bottom thereof and suitably packed as at l. Numeral 8 generally refers to the valve structure which consists of the cylindrical shell 9 clamped between the two headers Ill and H. The lower header H has a recess l2 therein upon which a suitable packing gasket is placed and against which the lower end of the shell 9 engages while the upper end of the shell engages against the packing plate I3. Bolt members l4 extend upwardly through openings in the header II and pass through the header l0 where they are equipped with nuts [5. One or more of these bolts l4 pass upwardly through the lower portion of the U-shaped bracket l6 through the leg por- 0 tions of which extends the pin ll, which pin also extends through the bell crank 18. The lower end of the bell crank I8 is connected by the pivotal link l9 to the threaded shank 20 which is screw threaded into the threaded opening 2| of the cage 22 which contains the valve body 23. Upon the cage 22 is the resilient valve plate 24 which is adapted to close off the outlet opening 25 in the header l0 when the float generally referred to by numeral 26 is in elevated position. When the float 26 lowers to the position shown in Figure 3 or lower, the water is free to pass through the opening 25. The water actually passes through and around the cage 22 to reach the opening 25. The float 26 consists of a, block 21 of wood which is preferably bored through as at 28 at various points soas to lighten the float and the ends of these bores are plugged as at 29 thus leaving air spaces 30. Plates 3| are bolted as at 32 to one end of the float block 21 and one of these plates 3| is hingedly connected as at 33 to the upper header I!) while the other plate 3i is hingedly connected as at 34 tothe arm 35 which in turn is pivotally connected as at 36 to the upper end of the bell crank I8.

It is possible that a small strainer 31 be placed over the discharge end of the supply pipe 6 as shown in Figures 2 and 5.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materi s may be resorted to without departing r65. the spirit and scope of the invention as claimed hereinafter.

Having thus described the invention, what is claimed is:--

1. A float of the character described comprising a block of wood provided with bores driven therethrough and'plug elements driven into the block to close the ends of the bores.

2. In a float valve construction a valve seat plate, a valve operating member movable through the plate, a bracket mounted on the plate, a bell crank rockably supported by the bracket and having its lower end attached to the valve operating member, an elongated float member, a hinge plate secured to the top and bottom sides of the float, a link between the upper end of the bell crank and the upper hinge plate on the float, and a hinging connection between the lower hinge plate and one end of the valve seat plate.
